The SCAR-L
The SCAR-H
The Special Operations Forces Combat Assault Rifle (SCAR)[10] is a modular rifle made by FN Herstal (FNH) for the Alliance Joint Military Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition.[11] This family of rifles consist of two main types. The SCAR-L, for "light", is chambered in the 5.56×45mm NATO cartridge and the SCAR-H, for "heavy", fires 7.62×51mm NATO. Both are available in Long Barrel and Close Quarters Combat variants. The SCAR is manufactured in two main versions; Light (SCAR-L, Mk 16 Mod 0) and Heavy (SCAR-H, Mk 17 Mod 0). The L version fires 5.56×45mm NATO using improved STANAG (M16) magazines. The H fires the more powerful 7.62×51mm NATO from a newly designed 20-round magazine. Different length barrels will be available for close quarters battle and for longer-range engagements. There is a LMG variant of the SCAR, the HAMR (Heat Adaptive Modular Rifle), which is also used by the Alliance of Nations (but only Ariadna and the Irken Republic as the M27 IAR is in most members)
